TILLAGE IMPLEMENT.

Application filed September 6, 1921. Serial No. 498,694.

This invention particularly relates to tractor-drawn plowing implements including mechanism controlled by an operator on the tractor and having definite cycles of movement derived from the forward travel ofthe implement, in one of which cycles of its movement the frame and the plowing members.

carried by the frame are lowered from a nonworking position to aworking position and in the next cycle of the said movement are raised from the working position to the nonworking position. Implements of the kind referred to have also included means by which the soil working members may be adjusted by an operative to variably determine their depth of penetration into the ground as is necessary in order that furrows of dlfterent depths may be selectively produced.

llnder date of December 15, 1919,'I filed in the United States Patent Office an application which has matured into Patent Number 1,606,132 dated November 11, 1926, and under date of September 6 1922, I filedm the United States Patent Ofiice an application which has matured into PatentNumber 1,643,519 dated-September 27,1927. The applications for these patents were pending concurrently with the instant application and set forth plowing implements of the kind hereinabove referred to. The implements embodied in my aforesaid applications contain certain elements and combinations of elements which I prefer to use in the mechanism upon which the instant application for patent is based. The mechanism constituting the present mvention differs from those set forth in my aforesaid applications in certain substantial respects among which may be mentioned (1) A correlation of parts by which opposite sides of the implement are supported, the depth of furrow is adjusted by correspondingly adjusting one side of the implement relatively to the other through the operation of a depth controlling member, and both sides of the implement are raised simultaneously or lowered simultaneously through the medium of power mechanism;

One side of the implement is supported by furrow wheels mounted upon the lower ends of substantially verticalshafts and the other side of the implement is supported by a land wheel mounted upon the lower endof a crank axle, which axle is rocked in one direction by one cycle ofth movement of the power means and is rocked in the other direction in the next cycle of the movement of the power means and is connected with both furrow wheel shafts by means of a somewhat particular nature for raising both furrow wheel shafts simultaneously when the land wheel axle is rockedin one direction and for lowering them simultaneously when the land wheel axle is rocked in the other direction.

The two respects which characterize the instant invention maybe several, that is, they are not essentially inter-related and need not be embodied in the one implement and hence it isnot my purpose to confine the scope of the protection, considered in its broadest aspects, to an implement having both of said characteristic features. As a matter of fact, however, I find that an implement having the features referred to has marked advantages and the mechanism which I have devised is of such nature that its elements are so correlated as to embody both of said features and in a most practicable way. In a general way, it may be stated that this mechanism includes a member having a changeable fulcrum about one of which it is moved under control of a depth adjusting lever to cause one side of the implement to be adjusted relatively to the other and about the other of which it is moved under control of the power mechanism to cause both sides of the implement to be moved at once. Other features embodied in the illustrated mechanism will be apparent from the following description.

It should be understood that while the drawings illustrate what I consider to be the best embodiment of my invention and while I shall minutely describe said embodiment, yet I am aware that changes may be made in details and salient features of the invention may be otherwise and variously embodied without departingfrom the spirit of the invention as defined by the scope of the appended claims.

Fig. IS a snnllar View, showing the relative positions of'the parts when adjusted for a shallow furrow with the. frame inworking posit-ion.

Fig. 7 is a detail view showing, in front elevation, the means connecting the landwheel with the lever which adjusts the mechanism for different depths of furrow; and

the rear furrow wheel and a part of its axle. v The'drawin'gs exemplify the invention as embodied in a plowing implement having three soil turning members 10 of the moldboard type,'but the number of said turning members may. be varied and they may be of a different type from that illustratedineluding disks--without departing from the spirit'of the invention as defined by appended claims.

Theframe may be of any construction suitabl'e'to the number and type of SOll turning The illustrated frame at the front by a member 14 and 'atthe rear by members to form a strong and rigid structure, and extending at the rear to different vertical-planes so that the ,memberslO, which are carried by the downwardly curved rear ends 11, 12 and 13 of the beams, respecl tively, will be'arranged d agonally with relation to'the frame, or in successively offset relations. I v The frame and soil turning members are carried by a land wheel 16, a front furrow wheel 17 and a rear furrow wheel 18. The

land wheel,16, is rotatably mounted on the inwardly extending end or spindle 19 of a c 'ank axle, which comprisesa crank in mber 20 extending rearwardly from said spindle 19,

and. a journal member 21 extending across the frame and rotatable upon a horizontal axis in a bearing 22 carried. by the frame. The forward furrow wheel. 1'? is rotatably mounted upon a spindle 23 extending suitably from the lower end of a shaft or axle 24, which is mounted to rotate upon a vertical axis in a suitable bearing 25 secured to'the frame. The rear furrow wheel 18 is rotatably mounted on a spindle 26 inwardly inclined from the lower end of a shaft or axle 27 which is mounted to rotate upon a vertical axis in a bearing 28 carried by a bracket 29 secured to the downwardly extending end 13 of the beam 13. The upper ends of the vertical axles 24 and 27 are provided with cranks 30 and 30 connected with each other by a link 31 where'- by guiding movement is transmitted from the forward axle 24 to the rear axle 27.

The illustrated means for raising the frame and soil working members from working position to transport positionand for lowering them from transport position to working position "includes a clutch having a driven member 32 and a driving member .33. This clutch is". preferably of the construction fully set forth in my before mentioned Patent Number 1,606,132 to which reference may be had for a full understanding thereof.

' Attention, however, is directed to the fact that in v the present implement the driven member 32 ismounted upon the spindle19 of the land wheel axle,'instead of upon the forward furrow wheel axle, the driving member being in such case formed asa part of the rub of'the land wheel 16, instead of the hub of the forward furrow, wheel. The driven member ofthe clutch is provided with arms 34,35, controlling a dog or pawl,not shown, which constitutes the element'through which the driven member is operatively connected to the driving member, and these arms are normally held in position which holds the pawl out of engagement with the driving memberby a pivoted latch 36 which is operand soilworlring members, all as in my said patent; This clutch is of a nature such that the frame and soil working members are lowered from transport position to working position, or raisedfrom working position to transport position, as the case may be, while the land wheel is mal'ring one-half of a full revolution, during which time the latchis held out of'engagement with the corresponding'arm 34, and is then automatically engaged with the other dog or pawl to thereby disengage the pawl from the driving member and hence free the driven member from the driving member.

The driven member of the clutch is connected to the frame by means which cause the cranlraxle, (by which the driven member is carried and upon which the driving member and land wheel are mounted) to swing forward or rearward in thc'operationof changing the height of the frame and soil turning members with relation to the ground, and the connections between the driven member of the clutch and frame include an adjusting lever, 38, which is operable to variably adjust the depth of plowing and is held in any one of a number of different positions, for said purpose, by a quadrant 39. In the present embodiment, I have shown a connection between the lever and driven-member 32, which comprises a pin or lug 40 extending from said driven member and a link ll extending from Lana-r633 plement having1a power lift mechanism operated by the land wheelas distinguished from a furrow wheel) whereby the frame andxsoil working members may be set for any one of a plurality of diiferent'dept-hs of furrow but will be returned to their normal transport position regardless of the depth-to which they were adjusted for working purposes. The means herein exemplified for the accomplishment of this very important purpose is as follows The rear end of the lever 38 is fixedly secured to a transverse shaft 42 to which there is also fixed .a'sleeve 43 having a crank 44 connected by a link 45 to the lowerend of 'a lever 46' which is pivoted intermediate its length, at 47, to a crank 48 fixedly connected to the member 21 of the crank axle. The pivotal connection of the link 45'to the lever 46 is marked 46 The-upper end of the lever 46 is pivoted at 46 to the confronting ends of two members, as the longitudinally movable rods 49 and 50, which are connected with the vertical shafts24 carried by the front and rear furrow wheels, respectively, by means of such nature that relative up and down movement between the frame and said shafts will take place when the upper end of the member 46 is swungforward or rearward. The particular exemplified connections between the rod 49 and the vertical shaft 24 of the forw rd furrow wheel, includes a bell crank lever formed by a crank 51 to which the forward end of the rod 49 is connected, .a shaft 52 which is journaled in the frame and towhich the lower end of'the crank 51 is attached and a second crank, 53, also attached to the shaft and extending forward therefrom. The crank 53 is connected with the shaft 24 preferablyby means identical with that set forth in thecompanion application, which has since matured into Patent Number 1,643,519, hereinbefore referred to, to which reference may be had for a fuller understanding. It is sufficient in this application to state that it includes a rod 54 whichfor purposes additional to its function of forming an element of a practical connection between the crank 53 and shaft 24, is threaded within a sleeve 55 whose lower end is pivoted at 56 to the crank 53, said'rod also extending'threugh a member 57 which is pivoted at 57 to a bracket 58, the rear end of which bracket forms a collar 58 through which the shaft 24 extends. Relative rotative movement of the collar 58 and shaft 24 is permitted, but relative up and down movements are prevented by collars 59 and 60 which are fastened to the shaft and are arranged, respectively, above and below the collar 58. V

In the illustratedembodiment of the invention, the longitudinally movable rod 50 has its rear end connected to a crank 61 extending from one end of a shaft 62 whose other end is provided with a second crank, 63, extending forward therefrom and connected, by link 64,190.21 bracket 65 in which the vertical shaft 27 of the rear furrow wheel is rotatably mounted. A collar 66, fixed upon the shaft 27 and mounted in a recess formed in the rearend of'the bracket, engages the upper and lower walls of said recess. The shaft 62 is journaled'in a bracket 67 secured to the rear end of the frame and said shaft, together with the cranks 61 and 63 forms a bell crank lever one arm of which is connected to the rod 50 and the other arm of which has connection with the shaft 27 in such manner as to cause relative up and down movement between said shaft and theframe, when the rod 50 is moved longitudinally, while permitting the shaft 27 to turn within the collar 66.

It will be understood that movement of the shafts 24 and 27 within the collars 58 and 66, respectively, is for the purpose of guiding the implement and that said parts rotate simultaneously when rotative movement is imparted to shaft 24, by reason of the connection formed by the cranks 30 and 30 and rod 31. As a means for rotating the shaft 24, there is provided at the forward end of the frame, a transverse bar 70 having a series of openings 71 through the rotative any one of which the rear end of a draft bar 72 may be connected. The lower end of the shaft 24 is provided with a crank 73, which is arranged substantially at right angles with relation to the crank 30 and is connected with the draft bar 72 by a rod 74 having a portion threaded in a nut 75 trunnionedupon the draft bar. This means permits lateral adjustment of the draft bar to accommodate different hitching points on different tractors.

When the frame and soil working members are in transport position, the parts are arranged as follows:

The lower surfaces of all the wheels are in substantially the same horizontal plane, assuming, of course, that the ground is substantially level; the driven member 32 of the clutch is in the position in which its pin 40 is at its highest point of travel (Figs. 3 and 4) the latch 36 is engaged with the arm 34 and acts to hold the pawl (not shown) in the driven member of the clutch out of engagement with the driving member of the clutch: the lever 38 is locked to the quadrant 39 (by dog 39 at the particular notch corresponding to the depth'of furrow to be pro- Y duced.

If a furrow of minimum depth is to be produced, the lever 38 is locked to the quadrant at the lowest notch of the quadrant (Fig. 3) and when the lever is in this position, the frame and the lower surfaces of the plow bodies occupy substantially horizontal positions, that is to say theframe is level and the lower surfaces of the plow bodies are in a plane substantially parallel with the plane 7 the minimum is to will to the driven member '32 of the clutch has notbeen turned about its axis on the spindle bodies are fixedly attached that the movement is operated.

ing wheels.

f, however, a furrow of greater depth than beproduced i (see Fig; 4f), the operator raises the outer end of the lever 381a distance corresponding; to the depth of furrow-to be madevand then locks it to the quadrant39 at the selected place on said quadrant. This movement of the lever 38 applies forceto the lower endof the lever 46, at the point 46, causing said lever to swing about its upper fulcrumat L6" (which remains stationary) and to apply'power in a rearward direction to the upper end of the crank a8, at the point 4L7, to turn the journal portion 21 ofthe 0 unit axle in its bearing on theframe and hence change the angle of the crank portion 20. of the land wheel'axle relatively to the frame, the land wheel correspondingly moving forward and upward. It be noted that in the operation referred of the'land wheel axle nor has any movement been imparted to the rods 49, ,50 which control the verticalv movements of the furrow wheels. The movement of the crank axle. however, has allowed the landside side of the frame to correspondingly approach the ground and when the movement of the lever 38 has been completed audit is again locked to the segment 39, thejlandsideside of the frame has been lowered, without correspondingly lowering the. furrow side thereof and without changing the travel of any of the parts which control the vertical distance traversed by the frame in its movement from transport to working position. The plow to the. frame so of the landside side of the latter toward the ground without similar movement or, the furrow side toward the ground, has brought their points nearer to the ground without lowering them bodily.

This lowering of the points of the plow bodies, raises the rear of the mold board and gives" the land side a closer position to the ground while the plow bodies are still in the non-tilling position and above the ground;

Since the operation of the clutch lowers the land side a substantially constant distance, the total drop of the land side initial drop caused bythe setting of the depth control lever plus the drop caused by the lowering of the land side when the clutch The operation subsequent forward travel causes a dropping of the plow bodies and a raisingof the furrow wheels until all are in the same plane and as the machine advances,the plow bodies and furrow wheels go below the surface of the 'unplowed land until the aforesaid plane isparallel .to-the surface of the land being lowed.-

1 \Vhen the adjustment has been. thus made equals the of the clutch and the frame and plow bodies are lowered-bodily from "transport non plowing position by power derived from the landwheel as follows:. '7' r,

The operator upon the tractor after the implement has been set in motion pulls upon the-cord 371thus disengaging the latch 36 from the arm 3%, thereby permitting the pawl (not shown) in the driven member 32 of the clutch to-beforced into engagement with the driving member of the clutch. The driven member of the'clutch is now cau'sedto make onehalf of a completerevolution with the land wheel 16 and is then automatically released from-the driving member by the engagement of the latch 36 with thexarm 35. During this movement, the pin or lug l0 projecting fromthe clutch meniber 32 travels from its highest to its lowest'position (it be ing remembered thatit is always in its highest position when the implement is in transport position, regardless of any adjustment made for depth of furrow) thus permitting the landside side of the, frame .to lower, the journal portion'Ql of the land wheel axle turning rearward in its bearing upon the frame and'the landwheel moving forward relatively to the frame while the landside side is being lowered. The vaxial movement of the "journal portion 21 of the l'andwheel axle causes its crank ltlto apply'force to the lever 46 at the point d7 thereby causing said lever to turn about its lower fulcrum, at 46 (held stationary by the'loe ked hand lever 38), thus causing the upper endof the lever to travel rearward and to act through the arms l9 and 50 and the described connections between said arms and the furrow wheels,

to raise the furrow wheelsand thereby lower the furrow side of th frame simultaneously with thelow'ering of the frame atthe landside side, thus lowering the frame and bodies bodily. v r

If afur-row of minimum depthis to be produced, theleverBS. is locked to the lowest notch of the quadrant 39, and when the lever is in this position the frame and the lower surfaces of the plow bodies occupy substantially horizontal positions. It may be mentionedhere that the depth offurrow is regulated by changing theangles ofthe lower surfaces of the supporting frame and soilturning members relatively to the'points of contact of the implement supporting members (land and furrow Wheels, as here illustrated) with the ground while said members are in transport position, it being understood that, if the lower surfaces of-the frame and soil turning members be inclined with relation to thepoints of contact of the implement supporting members with the land, a deeper cut will be produced than if the bottoms'of the low bodies were more nearly horizontal due to the fact that the plow bodies will keep cutting deeper into the groundvuntil the bottoms the thrust link position of of the plow bodies are caused to reach a substantially horizontal position on account of the travel of the land wheel on the surface of the ground,

lVhen the parts are moving from transport to working position, or vice versa, under the power of the land wheehthe land and furrow wheel mountings, consisting of the spin-,

dles which are carried, respectively, by the crank axle and the upright axle or shaft 24, move toward or from the plane of the frame which supports the soil working bits or members,and this motion is caused by the reversal of the operated clutch member 32 through 41 which has an eccentric connection with the clutch member and a swinging or pendulous connection with the lever 38, which latter, being locked at the desired adjustment, in effect forms a part of the frame. 'Hence, as the lower fulcrum point 46 -is held fixed by link 45, the swinging move ment of the crank 48, carried by the crank axle causes aswinging movement of the upper end of lever 46 andtransmission of verticalmovement to the front and rear furrow wheel mountings. Vfhereas, when the hand lever'38 is adjusted to vary. the furrow depth the landside of the frame the fulcrum of'the lever 46 is at its upper end, 46*, and the lower end swings to move crank 48 andhence the crank aide to adjust the land wheel mounting. V

- It should also be noted that the landside member of the soil working bits is located in the longitudinal plane of and in trailing or tracking relation with the land wheel to maximize the effect of the'landside adjustment of the frame in determining the furrow depth, and'to provide for this relative transverse compactness of arrangement the arm 20 of the crank axle is arranged inside or landward of the plane of the wheel and the beam 13 of the land side bit is offset landward in rear of theland side wheel.

I The forward furrow wheel follows the last furrow formed in the previous travel of the "machine, as the rear furrow wheel IOllOWS the'furrow formed by the landward'soil workmg member, and due to the arrangement above noted the adjustment by means of the hand'lever 3S-substantially controls the furrow depth without altering the relations of the elements which cooperate in what for conveniencemay be termed the transposition movement from working to -transport and r from transport 'to working position under the actuation of the land wheel.

An important agency in permitting this independence of furrow dept-h adjustment and'transposition movement is the element represented in the present embodiment of the invention by the changeable fulcra lever 4 6, wherein the mounting in relation to the means for effecting said independent movement is such that its fulcrum or axis of swinging or depth of penetration of the to a transverse vertical plane of the major diameter of the driven clutch member and hence varies'the path of the pin 40 to which the thrust link or pitman bar 41 is connected and therefore the vertical distance through which said pin travels and the framemoves in the transposition movement, this variation is compensated for by theshift-ing or readjustment of the rocking transmission element represented by the changeable fulcra lever 46 due to variations in the adjustment of the lever 38 which controls the ifurrow depth positioning of the soil working members to insure at all furrow depth adjustments a substantially uniform proportionate extent of transposition movement. it
